Description

  The present invention relates to an electrical connector that supports a contact and includes a plate-like contact support portion that is inserted into and removed from a mating connector in an insulating housing.

  As a conventional electrical connector, a plate-like contact support portion that supports a contact and is inserted / removed with a mating connector is provided in an insulating housing, and contacts are arranged on both upper and lower sides of the contact support portion so as to be multipolar. Is known. In such an electrical connector, a metal plate is held by the contact support portion in order to reinforce the contact support portion having a plate shape and low strength (for example, Patent Document 1).

  Such a metal plate is embedded and fixed in the contact support portion by being integrally formed in the housing. Specifically, the metal plate is set in a predetermined position in the cavity formed by the upper mold and the lower mold, and then the molten resin is filled into the cavity. At this time, in order to prevent the metal plate set in the mold from being displaced from a predetermined position due to the pressure when filling the resin, the molten resin is cavityd with the presser pin sandwiched from above and below. Fill inside. After the temperature of the resin is lowered and the resin is cured, the holding pin is removed to fix the metal plate to the contact support portion of the housing by integral molding. Then, the contacts are press-fitted and fixed in the housing, so that a part of the contacts is exposed and arranged on the outer surface of the contact support portion of the housing.

  However, in the conventional electrical connector, when the metal plate is fixed to the contact support portion of the housing by integral molding, it is necessary to hold the metal plate from above and below with the pressing pin. There is a problem that a space is created between the metal plate fixed to the part and the contact provided to be exposed on the surface of the contact support part, and an electrical failure occurs due to the presence of foreign matter or liquid in the space. . In particular, due to changes in the ambient temperature when using the electrical connector, moisture in the air in the space between the metal plate and the contact condenses, creating water droplets in the space between the metal plate and the contact, resulting in an electrical failure. There is a problem that it may occur. In addition, it is conceivable to reduce the above-described electrical problems by increasing the distance between the metal plate and the contact, but in this case, it is difficult to reduce the size and increase the density of the electrical connector. Has the problem.

  In addition, as another method of forming the contact support part in which an outer surface of the contact support part in which the metal plate is embedded as described above is formed by exposing a part of the contacts, There is a method of integrally forming including a contact in addition to a plate. Thus, the method of integrally forming including the contact is preferable from the viewpoint of productivity as compared with the method of press-fitting the contact. However, when the contacts are integrally molded, the contact set in the mold is displaced from the predetermined position due to the pressure when filling the resin and the flow of the resin. May decrease.

  The object of the present invention is to prevent electrical failure even when foreign matter or liquid is present in the space between the metal plate and the contact, and to reduce the size and increase the density. An electrical connector is provided. Further, according to another aspect, in the case where such an electrical connector is formed by integrally forming a contact in addition to the metal plate, it is to improve the arrangement position accuracy of the contact.

  An electrical connector according to the present invention includes an insulating housing having a plate-like contact support portion that extends forward from a rear wall and engages with a mating connector, and a connection embedded in an outer surface of the contact support portion. And a terminal part connected to the conductive part of the substrate, the conductive contact held in the housing, and spaced apart from the connection part in the plate thickness direction of the contact support part to the contact support part A metal plate to be fixed, and the metal plate includes an insulating portion at least in part, and the contact support portion extends in the plate thickness direction and has one end in the plate thickness direction. A portion that opens to the outer surface of the contact support portion, and includes a hole portion that exposes the insulating portion at the other end in the plate thickness direction but does not expose the metal plate. A side edge of the connecting portion; And characterized in that match.

  One end of the hole in the plate thickness direction opens to the outer surface of the contact support portion, and the insulating portion is exposed at the other end of the hole in the plate thickness direction while the metal plate is not exposed. When the moisture in the air in the hole of the contact support part condenses, etc., and liquid accumulates in the hole part, or when foreign matter enters the hole part of the contact support part, the metal plate and the connection part in the hole part Even when the distance to the metal plate is short, the metal plate and the connecting portion are prevented from being electrically short-circuited via liquid or foreign matter.

  An electrical connector manufacturing method according to the present invention includes an insulating housing having a plate-like contact support portion that extends forward from a rear wall and engages with a mating connector, and is embedded in an outer surface of the contact support portion. A conductive contact held by the housing, and spaced apart from the connection portion in the plate thickness direction of the contact support portion. In the method of manufacturing an electrical connector having a metal plate fixed to a support portion, a step of forming an insulating portion on at least a part of the metal plate, and the metal plate and the contact are provided in a predetermined cavity in a mold. A range in which the insulating portion of the metal plate is formed by the step of setting the position of the metal plate and a pressing pin disposed so that a part thereof is in contact with the side edge of the connecting portion Holding the mold in a mold, filling the mold with resin and forming the housing by integrally forming the metal plate and the contact, and extracting the pressing pin. And a step of forming a hole from the outer surface of the contact support portion to the insulating portion.

  When the metal plate and the contact are set at a predetermined position in the cavity and are integrally molded, the pressure at the time of filling the resin is reduced because a part of the pressing pin is in contact with the side edge of the contact connecting portion. The contact connecting portion is prevented from shifting from a predetermined position due to the influence of the resin flow. As a result, it is possible to improve the arrangement position accuracy particularly in the direction along the width direction of the contact. In addition, the hole formed by pulling out the pressing pin after integrally forming a part of the pressing pin in contact with the side edge of the contact connecting portion in this way is the side edge of the connecting portion of the outer periphery. In the abutting portion, the side edge of the connection portion coincides with the side portion.

  According to the present invention, even when foreign matter or liquid is present in the space between the metal plate and the contact, it is possible to prevent electrical failure and to reduce the size and increase the density. it can. In addition, it is possible to improve the contact placement accuracy when the contacts are integrally formed.
